1.Start off by cutting the bottom off of the bottle with a pair of scissors.
2.Now turn your bottle upside down into the vase.  It’s time to start layering.  First layer will be your cotton balls. You want to have 1-2 inches of cotton.  Next layer will be your activated charcoal. About an inch worth.
3.Overtop of the charcoal, add 2 inches of gravel. You can also use stones if you have no gravel. Your next layer will be 3-4 inches of sand. Since your sand is there to trap larger particles, the cleaner the sand the better this experiment will turn out. Lastly, add another layer of gravel.

Now take a nice big glass of water and dirty it up. Mix a good amount of dirt into it and turn it into mud. Pour your muddy water into the top of your water filter and watch it slowly saturate the layers and make its way through your filter into the glass beneath.
